    摘要: Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Each of a set of imagers produces a portion of the final image. Relay lenses then tile the individual image portions together into a combined image. Because the height of the individual imagers is smaller than the height of a monolithic imager, they can fit into a very thin device. The combined image has a resolution equal to the sum of the resolutions of the individual imagers. The individual images are tiled together within the microprojector itself rather than on a projection screen. This allows the tiling to be adjusted once at the factory and set forever. In some embodiments, the light created for use by the microprojector is split by a polarizing beamsplitter. Each resultant polarized beam is then sent to an imager. Another polarizing beamsplitter combines the individual images.

    摘要: Disclosed are a system and method for microprojection that uses a “reduced-height” imager to sequentially display a series of partial images within one frame time. The partial images visually combine on a projection surface (e.g., a screen or a wall) into one high-resolution projected image. As a result, the microprojector projects an image with a resolution equal to the sum of the resolutions of the individual partial images while avoiding the use of very small imager optics with their lowered efficiency. For example, one embodiment projects exactly two partial images during each frame. During a first state of operation, a “half-height” imager displays the odd-numbered lines of the projected image. During a second state of operation, the imager displays the even-numbered lines of the projected image. By quickly cycling through these two states, no image flickering between phases is visible, and the combined image appears as a seamless whole.

    摘要: A low profile projector (102) for handheld devices (100) comprise a spatial light modulator (400) that has an aspect ratio that is increased relative to a standard video format and relative to an image projected by the low profile projector. The reduced height of the spatial light modulator (400) allows it fit within a thin handheld electronic device (100). An anamorphic lens (604,700) reduces the aspect ratio of the projected image relative to the aspect ratio of the spatial light modulator (400).

    摘要: Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Light created for use by the microprojector is split by a polarization-sensitive element into a number of beams. Each polarized beam is then sent to an imager. Each imager modulates the light beam to produce a portion of the final image. Another polarization-sensitive element directs the individual image portions through a projection lens system so that when they are projected, the individual image portions tile together into a seamless projected image. This technique uses essentially all of the original light, doubling the lighting efficiency of previous devices. Because the height of the individual imagers is smaller than the height of a monolithic imager, they can fit into a very thin device. The combined image has a resolution equal to the sum of the resolutions of the individual imagers.

    摘要: A video projector includes a reduced size spatial light modulator (400) that spatially modulates light from a light source (502) according to only a portion (e.g., ½) of a video frame at a time. A beam steerer (508, 600, 1600) steers spatially modulated light from the spatial light modulator to a correspond region (e.g., upper half, lower half) of a projection screen/surface (512) and one or more lenses (506, 510, 702, 802, 1002, 1008, 1100, 1300, 1502) insure that the spatially light modulator (400) is imaged onto the projection screen/surface (512).

    摘要: Disclosed are image expanding lenses, display devices, and electronic devices incorporating the disclosed image expanding lenses. In accordance with a disclosed image expanding lens, the image viewed by the user is larger than the active area of the LCD panel underneath the lens, so that the border around, for example, the LCD display is hidden from viewing. The image expanding lenses may include a non-uniform transparent substrate, having for example, a wedge shape that may be the top surface of the display. The substrate in combination with prismatic films may bend the light output from an array of pixels so that the image hides the border of the display device. In this way, an electronic device can render an edgeless image to a viewer since the image of the electronic device is projected beyond an edge of the display device of the host electronic device.
